Sometimes you want clients to be authoritative (although rare).
Or choose any case you like.
Explain why I can’t do it without this hilariously elementary philosophy detached from real world dev.
No cheating! I get access to the same resources. Explain why I need ZKP.
> After doing a bit of research, we decided that the most common real world use cases of zero-knowledge proofs (age verification, crypto, etc) aren’t particularly interesting to us. We enjoyed the graphs and theory of computation and networked computing though. We hope you had fun playing around with interactive proofs too.
The inclusion of this statement makes your comments look rather bizarre and strangely combative by comparison. Maybe we can just enjoy a bit of math together?
If they had no clue who it was, like the typical http web, they could not allow a sender to be a prover, since they would not be able to verify their balance. At some point a balance inquiry would have to reveal who they are. It only works if you trust the banker.
Funny that not only are you ignorant you are violently confident in your ignorance. I suffer from this sometimes too so I get it. Get some help.
It relies on trusting that Alice’s request is valid. If Alice sends another proof, she will have a different balance. Alice decides what to send. The server blindly accepts it.
You actually don’t want that for a lot of security and that’s why nobody uses ZKP for passwords or really anywhere outside theory - dumb theory that doesn’t understand basic web dev. We already have hashing and databases. There is a narrow use case for trusting clients - like receiving updates from intranet or p2p devices - maybe you use ZKP to omit unnecessary pii. But that’s it. It’s not what you think it is.
Alice can send anything in any cryptographic scheme involving two parties, the only real safety in any of it is "are the odds of an accepted different value low enough to be impractical for an attacker". Does that apply here too?
Imagine such a bank. Or social media (impersonate anyone, just say you’re them on the request why not), or any website.
The “zero knowledge” part of the name checks out.
Also nice sock puppet.
If you understood it, you’d have more respect for systems that are not Turing complete (and know it / don’t want to be).
It’s a new word invented by people who don’t know hashing and databases already exist.
